Different
methods have been applied to date the mean residence time (MRT) of the baseflow
in the Quequen Grande River (QGR) in the Province of Buenos Aires.
These techniques include: the analysis of
the sinus signal of stable isotopes and the use of the code FLOWPC, the
measurement of the concentration of CFCs, and the measurement of noble gases
foe the water age calculation from the 3H of tritigenic origin.
Results indicate the stable isotopes are useful to obtain the MRT for
translatory flow, while CFCs are giving the MRT for baseflow. 3H
general values suggest the dominance of baseflow in streamwater.
